Morphological and Physiological Characteristics of PH5DP

Inbred maize line PH5DP is a yellow, flint-like dent maize inbred thatis best suited to be used as a female in the production of the firstgeneration F1 maize hybrids. Inbred maize line PH5DP is best adapted tothe Southcentral, Southwest, and Western areas of the United States, andcan be used to produce hybrids with approximately 119 maturity based onthe Comparative Relative Maturity Rating System for harvest moisture ofgrain. Inbred maize line PH5DP is a late maturing high yielding inbredthat demonstrates above average disease tolerance for Gray Leaf Spot,Northern Leaf Blight, Southern Leaf Blight, Stewarts Wilt, GibberellaEar Rot, Common Rust, and Southern Rust. Inbred PH5DP has above averagefood grade, hard textured kernels and has above average Staygreen. Inhybrid combination, inbred PH5DP demonstrates above average yields,above average disease tolerance and drought tolerance.

The inbred has shown uniformity and stability within the limits ofenvironmental influence for all the traits as described in the VarietyDescription Information (Table 1, found at the end of the section). Theinbred has been self-pollinated and ear-rowed a sufficient number ofgenerations with careful attention paid to uniformity of plant type toensure the homozygosity and phenotypic stability necessary for use incommercial hybrid seed production. The line has been increased both byhand and in isolated fields with continued observation for uniformity.No variant traits have been observed or are expected in PH5DP.

Inbred maize line PH5DP, being substantially homozygous, can bereproduced by planting seeds of the line, growing the resulting maizeplants under self-pollinating or sib-pollinating conditions withadequate isolation, and harvesting the resulting seed using techniquesfamiliar to the agricultural arts.

Genetic Marker Profile

To select and develop superior inbred parental lines for producinghybrids, it is necessary to identify and select genetically uniqueindividuals that occur in a segregating population. The segregatingpopulation is the result of a combination of crossover events plus theindependent assortment of specific combinations of alleles at many geneloci that results in specific and unique genotypes. The geneticvariation among individual progeny of a breeding cross allows for theidentification of rare and valuable new genotypes. Once identified, itis possible to utilize routine and predictable breeding methods todevelop progeny that retain the rare and valuable new genotypesdeveloped by the initial breeder.

Even if the entire genotypes of the parents of the breeding cross werecharacterized and a desired genotype known, only a few if anyindividuals having the desired genotype may be found in a largesegregating F2 population. It would be very unlikely that a breeder ofordinary skill in the art would be able to recreate the same line twicefrom the very same original parents as the breeder is unable to directhow the genomes combine or how they will interact with the environmentalconditions. This unpredictability results in the expenditure of largeamounts of research resources in the development of a superior new maizeinbred line. Once such a line is developed its value to society issubstantial since it is important to advance the germplasm base as awhole in order to maintain or improve traits such as yield, diseaseresistance, pest resistance and plant performance in extreme weatherconditions. Backcross trait conversions are routinely used to add ormodify one or a few traits of such a line and this further enhances itsvalue and usefulness to society.

Phenotypic traits exhibited by PH5DP can be used to characterize thegenetic contribution of PH5DP to progeny lines developed through the useof PH5DP. Quantitative traits including, but not limited to, yield,maturity, stay green, root lodging, stalk lodging, and early growth aretypically governed by multiple genes at multiple loci. PH5DP progenyplants that retain the same degree of phenotypic expression of thesequantitative traits as PH5DP have received significant genotypic andphenotypic contribution from PH5DP. This characterization is enhancedwhen such quantitative trait is not exhibited in non-PH5DP breedingmaterial used to developed the PH5DP progeny.

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile, which can identify plants of the same variety ora related variety or be used to determine or validate a pedigree.Genetic marker profiles can be obtained by techniques such asRestriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction(AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Amplified Fragment Length Polymorphisms(AFLPs), Simple Sequence Repeats (SSRs) which are also referred to asMicrosatellites, and Single Nucleotide Polymorphisms (SNPs). Forexample, see Berry, Don, et al., “Assessing Probability of AncestryUsing Simple Sequence Repeat Profiles: Applications to Maize Hybrids andInbreds”, Genetics, 2002, 161:813-824, which is incorporated byreference herein.

Particular markers used for these purposes are not limited to the set ofmarkers disclosed herein, but are envisioned to include any type ofmarker and marker profile which provides a means of distinguishingvarieties. In addition to being used for identification of Inbred LinePH5DP, a hybrid produced through the use of PH5DP, and theidentification or verification of pedigree for progeny plants producedthrough the use of PH5DP, the genetic marker profile is also useful infurther breeding and in developing backcross conversions.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. SSRs are genetic markers based on polymorphismsin repeated nucleotide sequences, such as microsatellites. A markersystem based on SSRs can be highly informative in linkage analysisrelative to other marker systems in that multiple alleles may bepresent. Another advantage of this type of marker is that, through useof flanking primers, detection of SSRs can be achieved, for example, bythe polymerase chain reaction (PCR), thereby eliminating the need forlabor-intensive Southern hybridization. The PCR™ detection is done byuse of two oligonucleotide primers flanking the polymorphic segment ofrepetitive DNA. Repeated cycles of heat denaturation of the DNA followedby annealing of the primers to their complementary sequences at lowtemperatures, and extension of the annealed primers with DNA polymerase,comprise the major part of the methodology.

Following amplification, markers can be scored by gel electrophoresis ofthe amplification products. Scoring of marker genotype is based on thesize of the amplified fragment as measured by molecular weight (MW)rounded to the nearest integer. While variation in the primer used or inlaboratory procedures can affect the reported molecular weight, relativevalues should remain constant regardless of the specific primer orlaboratory used. When comparing lines it is preferable if all SSRprofiles are performed in the same lab. The SSR analyses reported hereinwere conducted in-house at Pioneer Hi-Bred. An SSR service is availableto the public on a contractual basis by Paragen (formerly Celera AgGen)in Research Triangle Park, North Carolina.

Primers used for the SSRs reported herein are publicly available and maybe found in the Maize GDB using the World Wide Wed prefix followed bymaizegdb.org (maintained by the USDA Agricultural Research Service), inSharopova et al. (Plant Mol. Biol. 48(5-6):463-481), Lee et al (PlantMol. Biol. 48(5-6); 453-461), or may be constructed from sequences ifreported herein. Some marker information may be available from Paragen.

Map information is provided by bin number as reported in the Maize GDB.A bin number.xx designation indicates that the bin location on thatchromosome is not known. The bin number digits to the left of decimalpoint represent the chromosome on which such marker is located, and thedigits to the right of the decimal represent the location on suchchromosome. Any bin numbers reported it parenthesis represent other binlocations for such marker that have been reported in the literature oron the Maize GDB. Map positions are also available on the Maize GDB fora variety of different mapping populations.

The SSR profile of Inbred PH5DP can be found in Table 2 found at the endof this section. The profile can be used to identify hybrids comprisingPH5DP as a parent, since such hybrids will comprise two sets of allele,one set of which will be the same alleles as PH5DP. Because an inbred isessentially homozygous at all relevant loci, an inbred should, in almostall cases, have only one allele at each locus. In contrast, a geneticmarker profile of a hybrid should be the sum of those parents, e.g., ifone inbred parent had allele x at a particular locus, and the otherinbred parent had allele y the hybrid is x.y (heterozygous) byinference. Subsequent generations of progeny produced by selection andbreeding are expected to be of genotype x (homozygous), y (homozygous),or x.y (heterozygous) for that locus position. When the F1 plant is usedto produce an inbred, the inbred should be either x or y for thatallele.

Plants and plant parts substantially benefiting from the use of PH5DP intheir development such as PH5DP comprising a backcross conversion,transgene, or genetic sterility factor, may be identified by having amolecular marker profile with a high percent identity to PH5DP.

The SSR profile of PH5DP also can be used to identify essentiallyderived varieties and other progeny lines developed from the use ofPH5DP, as well as cells and other plant parts thereof. Progeny plantsand plant parts produced using PH5DP may be identified by having amolecular marker profile of at least 25%, 30%, 35%, 40%, 45%, 50%, 55%,60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%,74%, 75%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%,91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5% geneticcontribution from inbred line PH5DP.

Unique SSR Profiles

While determining the SSR genetic marker profile of the inbredsdescribed supra, several unique SSR profile loci sets were or may beidentified through further analysis which did not appear in eitherparent of such inbred.

Such unique SSR profiles may arise during the breeding process fromrecombination or mutation. A combination of several unique allelesprovides a means of identifying an inbred, a hybrid produced from suchinbred, and progeny produced from such inbred. Such progeny may befurther characterized as being within a pedigree distance of PH5DP, suchas within 1,2,3, 4 or 5 or less breeding crosses to a maize plant otherthan PH5DP or a plant that has PH5DP as a parent or other progenitor.Further unique molecular profiles may be identified with other moleculartools such as SNPs and RFLPs.

Each genetic marker profile represents a novel grouping of allelesunique to an inbred. Each of the unique SSR profiles that may be foundare referred to as a “loci set”.

Comparing PH5DP to Other Inbreds

A breeder uses various methods to help determine which plants should beselected from the segregating populations and ultimately which inbredlines will be used to develop hybrids for commercialization. In additionto the knowledge of the germplasm and other skills the breeder uses, apart of the selection process is dependent on experimental designcoupled with the use of statistical analysis. Experimental design andstatistical analysis are used to help determine which plants, whichfamily of plants, and finally which inbred lines and hybrid combinationsare significantly better or different for one or more traits ofinterest. Experimental design methods are used to assess error so thatdifferences between two inbred lines or two hybrid lines can be moreaccurately determined. Statistical analysis includes the calculation ofmean values, determination of the statistical significance of thesources of variation, and the calculation of the appropriate variancecomponents. Either a five or a one percent significance level iscustomarily used to determine whether a difference that occurs for agiven trait is real or due to the environment or experimental error. Oneof ordinary skill in the art of plant breeding would know how toevaluate the traits of two plant varieties to determine if there is nosignificant difference between the two traits expressed by thosevarieties. For example, see Fehr, Walt, Principles of CultivarDevelopment, p. 261-286 (1987) which is incorporated herein byreference. Mean trait values may be used to determine whether traitdifferences are significant, and preferably the traits are measured onplants grown under the same environmental conditions.

In Tables 3A-3F, data from traits and characteristics of inbred maizeline PH5DP per se are given and compared to other maize inbred lines.

Inbred by Tester comparisons are also used to evaluate two inbreds.Combined inbred by tester comparison results can be used to distinguishtwo inbred lines while also providing information about the combiningability of the inbreds used.

Tables 4A and 4B compare PH5DP to two other inbreds, when each inbred iscrossed to the same tester lines.

Methods of Introducing a New Gene or Trait into PH5DP.

Field crops are bred through techniques that take advantage of theplant's method of pollination. A plant is self-pollinated if pollen fromone flower is transferred to the same or another flower of the sameplant. A plant is sib-pollinated when individuals within the same familyor line are used for pollination. A plant is cross-pollinated if thepollen comes from a flower on a different plant from a different familyor line. The terms “cross-pollination” and “out-cross” as used herein donot include self-pollination or sib-pollination.

Maize (zea mays L.), often referred to as corn in the United States, canbe bred by both self-pollination and cross-pollination techniques. Maizehas separate male and female flowers on the same plant, located on thetassel and the ear, respectively. Natural or open pollination occurs inmaize when wind blows pollen from the tassels to the silks that protrudefrom the tops of the ears.

Plants that have been self-pollinated and selected for type for manygenerations become homozygous at almost all gene loci and produce auniform population of true breeding progeny. A cross between twodifferent homozygous lines produces a uniform population of hybridplants that may be heterozygous for many gene loci. A cross of twoplants; each heterozygous at a number of gene loci, will produce apopulation of hybrid plants that differ genetically and will not beuniform.

One possible method of introducing a new gene or trait into PH5DP isproducing a backcross conversion of PH5DP. A backcross conversion occurswhen DNA sequences are introduced through traditional(non-transformation) breeding techniques, such as backcrossing (Hallaueret al, 1988). DNA sequences, whether naturally occurring or transgenes,may be introduced using these traditional breeding techniques. Abackcross conversion may produce a plant with a trait conversion in atleast one or more crosses, including at least 2 crosses, at least 3crosses, at least 4 crosses, and the like. Molecular marker assistedbreeding or selection may be utilized to reduce the number ofbackcrosses necessary to achieve the backcross conversion. The termbackcross conversion is also referred to in the art as a single locusconversion. Reference is made to US 2002/0062506A1 for a detaileddiscussion of single locus conversions and traits that may beincorporated into PH5DP through backcross conversion. Desired traitstransferred through this process include, but are not limited to, waxystarch, grain color, nutritional enhancements, altered fatty acidprofile, increased digestibility, low phytate, industrial enhancements,disease resistance, insect resistance, herbicide resistance and yieldenhancements. The trait of interest is transferred from the donor parentto the recurrent parent, in this case, the maize plant disclosed herein.The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is accomplished by direct selection for a traitassociated with a dominant allele. Selection of progeny for a trait thatis transferred via a recessive allele, such as the waxy starchcharacteristic, requires growing and selfing the first backcrossgeneration to determine which plants carry the recessive alleles.Recessive traits may require additional progeny testing in successivebackcross generations to determine the presence of the gene of interest.Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. While occasionally additionalpolynucleotide sequences or genes are transferred along with thebackcross conversion, this is an insubstantial; change to the variety,and backcross conversion lines are easily developed without undueexperimentation. Hallauer et al. (1998, page 472) states that “Forsingle gene traits that are relatively easy to classify, the backcrossmethod is effective and relatively easy to manage.” Poehlman et al.(1995, page 334) states that “A backcross-derived inbred line fits intothe same hybrid combination as the recurrent parent inbred line andcontributes the effect of the additional gene added through thebackcross.”

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Scientists in thefield of plant biology developed a strong interest in engineering thegenome of plants to contain and express foreign genetic elements, oradditional, or modified versions of native or endogenous geneticelements in order to alter the traits of a plant in a specific manner.Any DNA sequences, whether from a different species or from the samespecies, that are inserted into the genome using transformation arereferred to herein collectively as “transgenes”. A transformed plant maycontain at least one transgene but could contain at least 1, 2, 3, 4, 5,6, 7, 8, 9, 10 and/or no more than 15, 14, 13, 12, 11, 10, 9, 8, 7, 6,5, 4, 3, or 2. Over the last fifteen to twenty years several methods forproducing transgenic plants have been developed, and the presentinvention, in particular embodiments, also relates to transformedversions of the claimed inbred maize line PH5DP as well as hybridcombinations thereof.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick,B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages67-88 and Armstrong, “The First Decade of Maize Transformation: A Reviewand Future Perspective” (Maydica 44:101-109, 1999). In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation” in Methods inPlant Molecular Biology and Biotechnology, Glick, B. R. and Thompson, J.E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119.

The most prevalent types of plant transformation involve theconstruction of an expression vector. Such a vector comprises a DNAsequence that contains a gene under the control of or operatively linkedto a regulatory element, for example a promoter. The vector may containone or more genes and one or more regulatory elements.

A genetic trait which has been engineered into a particular maize plantusing transformation techniques, could be moved into another line usingtraditional breeding techniques that are well known in the plantbreeding arts. For example, a backcrossing approach is commonly used tomove a transgene from a transformed maize plant to an elite inbred line,and the resulting progeny would then comprise the transgene(s). Also, ifan inbred line was used for the transformation then the transgenicplants could be crossed to a different inbred in order to produce atransgenic hybrid maize plant. As used herein, “crossing” can refer to asimple X by Y cross, or the process of backcrossing, depending on thecontext.

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences. Seethe traits, genes and transforming methods listed in U.S. Pat. No.6,118,055, which are herein incorporated by reference.

With transgenic plants according to the present invention, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein then can beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem. 114: 92-6(1981). In one embodiment, the biomass of interest is seed.

A genetic map can be generated, primarily via conventional RestrictionFragment Length Polymorphisms (RFLP), Polymerase Chain Reaction (PCR)analysis, and Simple Sequence Repeats (SSR) and Single NucleotidePolymorphisms (SNP) which identifies the approximate chromosomallocation of the integrated DNA molecule. For exemplary methodologies inthis regard, see Glick and Thompson, METHODS IN PLANT MOLECULAR BIOLOGYAND BIOTECHNOLOGY 269-284 (CRC Press, Boca Raton, 1993).

Wang et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome”, Science,280:1077-1082, 1998, and similar capabilities are becoming increasinglyavailable for the corn genome. Map information concerning chromosomallocation is useful for proprietary protection of a subject transgenicplant. If unauthorized propagation is undertaken and crosses made withother germplasm, the map of the integration region can be compared tosimilar maps for suspect plants, to determine if the latter have acommon parentage with the subject plant. Map comparisons would involvehybridizations, RFLP, PCR, SSR and sequencing, all of which areconventional techniques. SNP's may also be used alone or in combinationwith other techniques.

Likewise, by means of the present invention, plants can be geneticallyengineered to express various phenotypes of agronomic interest. Throughthe transformation of maize the expression of genes can be modulated toenhance disease resistance, insect resistance, herbicide resistance,agronomic traits as well as grain quality traits. Transformation canalso be used to insert DNA sequences which control or help controlmale-sterility. DNA sequences native to maize as well as non-native DNAsequences can be transformed into maize and used to modulate levels ofnative or non-native proteins. Anti-sense technology, various promoters,targeting sequences, enhancing sequences, and other DNA sequences can beinserted into the maize genome for the purpose of modulating theexpression of proteins. Exemplary transgenes implicated in this regardinclude, but are not limited to, those categorized below.

De Greef et al., Bio/Technology 7: 61 (1989), describe theproduction of transgenic plants that express chimeric bar genes codingfor phosphinothricin acetyl transferase activity. See also, U.S. Pat.Nos. 5,969,213; 5,489,520; 5,550,318; 5,874,265; 5,919,675; 5,561,236;5,648,477; 5,646,024; 6,177,616 B1; and 5,879,903, which areincorporated herein by reference for this purpose. Exemplary of genesconferring resistance to phenoxy proprionic acids and cycloshexones,such as sethoxydim and haloxyfop, are the Acc1-S1, Acc1-S2 and Acc1-S3genes described by Marshall et al., Theor. Appl. Genet. 83: 435 (1992).

(C) A herbicide that inhibits photosynthesis, such as a triazine (psbAand gs+genes) and a benzonitrile (nitrilase gene). Przibilla et al.,Plant Cell 3: 169 (1991), describe the transformation of Chlamydomonaswith plasmids encoding mutant psbA genes. Nucleotide sequences fornitrilase genes are disclosed in U.S. Pat. No. 4,810,648 to Stalker, andDNA molecules containing these genes are available under ATCC AccessionNos. 53435, 67441 and 67442. Cloning and expression of DNA coding for aglutathione S-transferase is described by Hayes et al., Biochem. J. 285:173 (1992).

(D) Acetohydroxy acid synthase, which has been found to make plants thatexpress this enzyme resistant to multiple types of herbicides, has beenintroduced into a variety of plants (see, e.g., Hattori et al. (1995)Mol Gen Genet 246:419).

(E) Protoporphyrinogen oxidase (protox) is necessary for the productionof chlorophyll, which is necessary for all plant survival. The protoxenzyme serves as the target for a variety of herbicidal compounds. Theseherbicides also inhibit growth of all the different species of plantspresent, causing their total destruction. The development of plantscontaining altered protox activity which are resistant to theseherbicides are described in U.S. Pat. Nos. 6,288,306 B1; 6,282,837 B1;and 5,767,373; and international publication WO 01/12825, which areincorporated herein by reference for this purpose.

3. Transgenes that Confer or Contribute to a Grain Trait, Such as:

(A) Modified fatty acid metabolism, for example, by transforming a plantwith an antisense gene of stearyl-ACP desaturase to increase stearicacid content of the plant. See Knultzon et al, Proc. Natl. Acad. Sci.USA 89: 2624 (1992).

(B) Decreased Phytate Content

-   -   (1) Introduction of a phytase-encoding gene would enhance        breakdown of phytate, adding more free phosphate to the        transformed plant. For example, see Van Hartingsveldt et al.,        Gene 127: 87 (1993), for a disclosure of the nucleotide sequence        of an Aspergillus niger phytase gene.    -   (2) A gene could be introduced that reduces phytate content. In        maize, this, for example, could be accomplished, by cloning and        then reintroducing DNA associated with the single allele which        is responsible for maize mutants characterized by low levels of        phytic acid. See Raboy et al., Maydica 35: 383 (1990).

(C) Modified carbohydrate composition effected, for example, bytransforming plants with a gene coding for an enzyme that alters thebranching pattern of starch. See Shiroza et al., J. Bacteriol. 170: 810(1988) (nucleotide sequence of Streptococcus mutans fructosyltransferasegene), Steinmetz et al, Mol. Gen. Genet. 200: 220 (1985) (nucleotidesequence of Bacillus subtilis levansucrase gene), Pen et al.,Bio/Technology 10: 292 (1992) (production of transgenic plants thatexpress Bacillus licheniformis α-amylase), Elliot et al, Plant Molec.Biol 21: 515 (1993) (nucleotide sequences of tomato invertase genes),Søgaard et al., J. Biol. Chem. 268: 22480 (1993) (site-directedmutagenesis of barley α-amylase gene), and Fisher et al., Plant Physiol.102: 1045 (1993) (maize endosperm starch branching enzyme II).

PH5DP Inbreds that are Male Sterile

Hybrid seed production requires elimination or inactivation of pollenproduced by the female inbred parent. Incomplete removal or inactivationof the pollen provides the potential for self-pollination. A reliablemethod of controlling male fertility in plants offers the opportunityfor improved plant breeding. This is especially true for development ofmaize hybrids, which relies upon some sort of male sterility system. Itshould be understood that PH5DP can be produced in a male-sterile form.There are several ways in which a maize plant can be manipulated so thatit is male sterile. These include use of manual or mechanicalemasculation (or detasseling), use of one or more genetic factors thatconfer male sterility, including cytoplasmic genetic and/or nucleargenetic male sterility, use of gametocides and the like. A male sterileinbred designated PH5DP may include one or more genetic factors, whichresult in cytoplasmic genetic and/or nuclear genetic male sterility.Such embodiments are also within the scope of the present claims. Theterm manipulated to be male sterile refers to the use of any availabletechniques to produce a male sterile version of maize line PH5DP. Themale sterility may be either partial or complete male sterility.

Hybrid maize seed is often produced by a male sterility systemincorporating manual or mechanical detasseling. Alternate strips of twomaize inbreds are planted in a field, and the pollen-bearing tassels areremoved from one of the inbreds (female). Provided that there issufficient isolation from sources of foreign maize pollen, the ears ofthe detasseled inbred will be fertilized only from the other inbred(male), and the resulting seed is therefore hybrid and will form hybridplants.

The laborious detasseling process can be avoided by using cytoplasmicmale-sterile (CMS) inbreds. Plants of a CMS inbred are male sterile as aresult of factors resulting from the cytoplasmic, as opposed to thenuclear, genome. Thus, this characteristic is inherited exclusivelythrough the female parent in maize plants, since only the femaleprovides cytoplasm to the fertilized seed. CMS plants are fertilizedwith pollen from another inbred that is not male-sterile. Pollen fromthe second inbred may or may not contribute genes that make the hybridplants male-fertile, and either option may be preferred depending on theintended use of the hybrid. The same hybrid seed, a portion producedfrom detasseled fertile maize and a portion produced using the CMSsystem, can be blended to insure that adequate pollen loads areavailable for fertilization when the hybrid plants are grown.

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations asdescribed by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al., of Pioneer Hi-Bred, U.S.Pat. No. 5,432,068, have developed a system of nuclear male sterilitywhich includes: identifying a gene which is critical to male fertility;silencing this native gene which is critical to male fertility; removingthe native promoter from the essential male fertility gene and replacingit with an inducible promoter; inserting this genetically engineeredgene back into the plant; and thus creating a plant that is male sterilebecause the inducible promoter is not “on” resulting in the malefertility gene not being transcribed. Fertility is restored by inducing,or turning “on”, the promoter, which in turn allows the gene thatconfers male fertility to be transcribed.

These, and the other methods of conferring genetic male sterility in theart, each possess their own benefits and drawbacks. Some other methodsuse a variety of approaches such as delivering into the plant a geneencoding a cytotoxic substance associated with a male tissue specificpromoter or an antisense system in which a gene critical to fertility isidentified and an antisense to that gene is inserted in the plant (see:Fabinjanski, et al. EPO 89/3010153.8 publication no. 329,308 and PCTapplication PCT/CA90/00037 published as WO 90/08828).

Another system for controlling male sterility makes use of gametocides.Gametocides are not a genetic system, but rather a topical applicationof chemicals. These chemicals affect cells that are critical to malefertility. The application of these chemicals affects fertility in theplants only for the growing season in which the gametocide is applied(see Carlson, Glenn R., U.S. Pat. No. 4,936,904). Application of thegametocide, timing of the application and genotype specificity oftenlimit the usefulness of the approach and it is not appropriate in allsituations.

Incomplete control over male fertility may result in self-pollinatedseed being unintentionally harvested and packaged with hybrid seed. Themale parent is grown next to the female parent in the field, so there isthe very low probability that the male selfed seed could beunintentionally harvested and packaged with the hybrid seed. Once theseed from the hybrid bag is planted, it is possible to identify andselect these self-pollinated plants. These self-pollinated plants willbe genetically equivalent to one of the inbred lines used to produce thehybrid. Though the possibility of inbreds being included hybrid seedbags exists, the occurrence is very low because much care is taken toavoid such inclusions. It is worth noting that hybrid seed is sold togrowers for the production of grain or forage and not for breeding orseed production.

These self-pollinated plants can be identified and selected by oneskilled in the art due to their decreased vigor when compared to thehybrid. Inbreds are identified by their less vigorous appearance forvegetative and/or reproductive characteristics, including shorter plantheight, small ear: size, ear and kernel shape, cob color, or othercharacteristics.

Identification of these self-pollinated lines can also be accomplishedthrough molecular marker analyses. See, “The Identification of FemaleSelfs in Hybrid Maize: A Comparison Using Electrophoresis andMorphology”, Smith, J. S. C. and Wych, R. D., Seed Science andTechnology 14, pp. 1-8 (1995), the disclosure of which is expresslyincorporated herein by reference. Through these technologies, thehomozygosity of the self pollinated line can be verified by analyzingallelic composition at various loci along the genome. Those methodsallow for rapid identification of the invention disclosed herein.

Development of Maize Hybrids Using PH5DP

A single cross maize hybrid results from the cross of two inbred lines,each of which has a genotype that complements the genotype of the other.The hybrid progeny of the first generation is designated F1. In thedevelopment of commercial hybrids in a maize plant breeding program,only the F1 hybrid plants are sought. F1 hybrids are more vigorous thantheir inbred parents. This hybrid vigor, or heterosis, can be manifestedin many polygenic traits, including increased vegetative growth andincreased yield.

PH5DP may be used to produce hybrid maize seed. One such embodiment isthe method of crossing inbred maize line PH5DP with another maize plant,such as a different maize inbred line, to form a first generation F1hybrid plant. The first generation F1 hybrid plant produced by thismethod is also an embodiment of the invention. This first generation F1plant will comprise an essentially complete set of the alleles of inbredline PH5DP. One of ordinary skill in the art can utilize either breederbooks or molecular methods to identify a particular F1 hybrid plantproduced using inbred line PH5DP, and any such individual plant is alsoencompassed by this invention. These embodiments also cover use of thesemethods with transgenic, male sterile and/or backcross conversions ofinbred line PH5DP.

The development of a maize hybrid in a maize plant breeding programinvolves three steps: (1) the selection of plants from various germplasmpools for initial breeding crosses; (2) the selfing of the selectedplants from the breeding crosses for several generations to produce aseries of inbred lines, which, although different from each other, breedtrue and are highly uniform; and (3) crossing the selected inbred lineswith different inbred lines to produce the hybrids. During theinbreeding process in maize, the vigor of the lines decreases. Vigor isrestored when two different inbred lines are crossed to produce thehybrid. An important consequence of the homozygosity and homogeneity ofthe inbred lines is that the hybrid between a defined pair of inbredswill always be the same. Once the inbreds that give a superior hybridhave been identified, the hybrid seed can be reproduced indefinitely aslong as the homogeneity of the inbred parents is maintained.

PH5DP may be used to produce a single cross hybrid, a three-way hybridor a double cross hybrid. A single cross hybrid is produced when twoinbred lines are crossed to produce the F1 progeny. A double crosshybrid is produced from four inbred lines crossed in pairs (A×B and C×D)and then the two F1 hybrids are crossed again (A×B)×(C×D). A three-waycross hybrid is produced from three inbred lines where two of the inbredlines are crossed (A×B) and then the resulting F1 hybrid is crossed withthe third inbred (A×B)×C. Much of the hybrid vigor and uniformityexhibited by F1 hybrids is lost in the next generation (F2).Consequently, seed produced from hybrids is not used for planting stock.

Inbred by Tester Comparisons

Combining ability of a line, as well as the performance of the line perse, is a factor in the selection of improved maize inbreds. Combiningability refers to a line's contribution as a parent when crossed withother lines to form hybrids. The hybrids formed for the purpose ofselecting superior lines are designated as test crosses. One way ofmeasuring combining ability is by using values based in part on theoverall mean of a number of test crosses. This mean may be adjusted toremove environmental effects and it is adjusted for known geneticrelationships among the lines.

Combining Ability Data

A general combining ability report for inbred PH5DP is provided in Table5. Table 5 shows overall mean values of traits from numerous F1 linesproduced by crosses between inbred PH5DP and other maize lines. Table 5demonstrates that inbred PH5DP shows good general combining ability forhybrid production.

A specific combining ability report for inbred PH5DP is provided inTables 5A and 5B. Tables 5A and 5B show mean values of traits fromnumerous individual F1 lines produced by crosses between inbred PH5DPand other maize lines.

Hybrid Comparisons

The results in Tables 6A-6D compare a hybrid for which inbred PH5DP is aparent and four other maize hybrids.

Using PH5DP to Develop Other Maize Inbreds

Inbred maize lines are typically developed for use in the production ofhybrid maize lines. However, PH5DP could also be used to derive newmaize inbred lines. Inbred maize lines preferably should be highlyhomogeneous, substantially homozygous and reproducible to be useful asparents of commercial hybrids. Plant breeding techniques known in theart and used in a maize plant breeding program include, but are notlimited to, recurrent selection, mass selection, bulk selection, massselection, backcrossing, pedigree breeding, open pollination breeding,restriction fragment length polymorphism enhanced selection, geneticmarker enhanced selection, making double haploids, and transformation.Often combinations of these techniques are used. The development ofmaize hybrids in a maize plant breeding program requires, in general,the development of homozygous inbred lines, the crossing of these lines,and the evaluation of the crosses. There are many analytical methodsavailable to evaluate the result of a cross. The oldest and mosttraditional method of analysis is the observation of phenotypic traits.Alternatively, the genotype of a plant can be examined.

Using PH5DP in a Breeding Program

This invention is directed to methods for producing a maize plant bycrossing a first parent maize plant with a second parent maize plantwherein either the first or second parent maize plant is an inbred maizeplant of the line PH5DP. Thus, any such methods using the inbred maizeline PH5DP are part of this invention: selfing, sibbing, backcrosses,mass selection, bulk selection, hybrid production, crosses topopulations, and the like. All plants produced using inbred maize linePH5DP as a parent are within the scope of this invention, includingplants essentially derived from inbred maize line PH5DP, as such term isdefined in 7 U.S.C. § 2104(a)(3) of the Plant Variety Protection Act,which definition is hereby incorporated by reference. This also includesprogeny plants and parts thereof with at least one ancestor that isPH5DP, and more specifically, where the pedigree of the progeny includes1, 2, 3, 4, and/or 5 or less breeding crosses to a maize plant otherthan PH5DP or a plant that has PH5DP as a parent or other progenitor.All breeders of ordinary skill in the art maintain pedigree records oftheir breeding programs. These pedigree records contain a detaileddescription of the breeding process, including a listing of all parentallines used in the breeding process and information on how such line wasused. Thus, a breeder would know if PH5DP were used in the developmentof a progeny line, and would also know how many crosses to a line otherthan PH5DP or line with PH5DP as a parent or other progenitor were madein the development of any progeny line. The inbred maize line may alsobe used in crosses with other, different, maize inbreds to produce firstgeneration (F1) maize hybrid seeds and plants with superiorcharacteristics.

Pedigree Breeding

Pedigree breeding starts with the crossing of two genotypes, such asPH5DP and one other elite inbred line having one or more desirablecharacteristics that is lacking or which complements PH5DP. If the twooriginal parents do not provide all the desired characteristics, othersources can be included in the breeding population. In the pedigreemethod, superior plants are selfed and selected in successive filialgenerations. In the succeeding filial generations the heterozygouscondition gives way to homogeneous lines as a result of self-pollinationand selection. Typically in the pedigree method of breeding, five ormore successive filial generations of selfing and selection ispracticed: F1→F2; F2→F3; F3→F4; F4→F₅, etc. After a sufficient amount ofinbreeding, successive filial generations will serve to increase seed ofthe developed inbred. Preferably, an inbred line comprises homozygousalleles at about 95% or more of its loci.

Backcrossing

In addition to being used to create a backcross conversion, backcrossingcan also be used to modify PH5DP and a hybrid that is made using themodified PH5DP. As discussed previously, backcrossing can be used totransfer a specific desirable trait from one line, the donor parent, toan inbred called the recurrent parent which has overall good agronomiccharacteristics yet lacks that desirable trait. This transfer of thedesirable trait into an inbred with overall good agronomiccharacteristics can be accomplished by first crossing a recurrent parentand a donor parent (non-recurrent parent). The progeny of this cross isthen mated back to the recurrent parent followed by selection in theresultant progeny for the desired trait to be transferred from thenon-recurrent parent as well as selection for the characteristics of therecurrent parent. Typically after four or more backcross generationswith selection for the desired trait and the characteristics of therecurrent parent, the progeny will contain essentially all genes of therecurrent parent except for the genes controlling the desired trait.However, the number of backcross generations can be less if molecularmarkers are used during selection or elite germplasm is used as thedonor parent.

The last backcross generation is then selfed to give pure breedingprogeny for the gene(s) being transferred. In addition to the abovedescribed use, backcrossing can be used in conjunction with pedigreebreeding to develop new inbred lines. For example, an F1 can be createdthat is backcrossed to one of its parent lines to create a BC1, BC2,BC3, etc. Progeny are selfed and selected so that the newly developedinbred has many of the attributes of the recurrent parent and some ofthe desired attributes of the non-recurrent parent. This approachleverages the value and strengths of the recurrent parent for use in newhybrids and breeding, and has very significant value for a breeder.

Recurrent Selection and Mass Selection

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. PH5DP can be used in a recurrentselection program to improve the population. The method entailsindividual plants cross pollinating with each other to form progenywhich are then grown. The superior progeny are then selected by anynumber of methods, which include individual plant, half-sib progeny,full-sib progeny, selfed progeny and topcrossing. The selected progenyare cross pollinated with each other to form progeny for anotherpopulation. This population is planted and again superior plants areselected to cross pollinate with each other. Recurrent selection is acyclical process and therefore can be repeated as many times as desired.The objective of recurrent selection is to improve the traits of apopulation. The improved population can then be used as a source ofbreeding material to obtain inbred lines to be used in hybrids or usedas parents for a synthetic cultivar. A synthetic cultivar is theresultant progeny formed by the intercrossing of several selectedinbreds. Mass selection is a useful technique when used in conjunctionwith molecular marker enhanced selection. In mass selection seeds fromindividuals are selected based on phenotype. These selected seeds arethen bulked and used to grow the next generation. Similarly, bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of directed pollination, open pollinationcould be used as part of the breeding program.

Mutation Breeding

Mutation breeding is one of many methods that could be used to introducenew traits into PH5DP. Mutations that occur spontaneously or areartificially induced can be useful sources of variability for a plantbreeder. The goal of artificial mutagenesis is to increase the rate ofmutation for a desired characteristic. Mutation rates can be increasedby many different means including temperature, long-term seed storage,tissue culture conditions, radiation; such as X-rays, Gamma rays (e.g.cobalt 60 or cesium 137), neutrons, (product of nuclear fission byuranium 235 in an atomic reactor), Beta radiation (emitted fromradioisotopes such as phosphorus 32 or carbon 14), or ultravioletradiation (preferably from 2500 to 2900 nm), or chemical mutagens (suchas base analogues (5-bromo-uracil), related compounds (8-ethoxycaffeine), antibiotics (streptonigrin), alkylating agents (sulfurmustards, nitrogen mustards, epoxides, ethylenamines, sulfates,sulfonates, sulfones, lactones), azide, hydroxylamine, nitrous acid, oracridines. Once a desired trait is observed through mutagenesis thetrait may then be incorporated into existing germplasm by traditionalbreeding techniques. Details of mutation breeding can be found in“Principals of Cultivar Development” Fehr, 1993 Macmillan PublishingCompany the disclosure of which is incorporated herein by reference.

Breeding with Molecular Markers

Molecular markers, which includes markers identified through the use oftechniques such as Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats(SSRs) and Single Nucleotide Polymorphisms (SNPs), may be used in plantbreeding methods utilizing PH5DP.

Isozyme Electrophoresis and RFLPs as discussed in Lee, M., “Inbred Linesof Maize and Their Molecular Markers,” The Maize Handbook,(Springer-Verlag, New York, Inc. 1994, at 423-432) incorporated hereinby reference for this purpose, have been widely used to determinegenetic composition. Isozyme Electrophoresis has a relatively low numberof available markers and a low number of allelic variants among maizeinbreds. RFLPs allow more discrimination because they have a higherdegree of allelic variation in maize and a larger number of markers canbe found. Both of these methods have been eclipsed by SSRs as discussedin Smith et al., “An evaluation of the utility of SSR loci as molecularmarkers in maize (Zea mays L.): comparisons with data from RFLPs andpedigree”, Theoretical and Applied Genetics (1997) vol. 95 at 163-173and by Pejic et al., “Comparative analysis of genetic similarity amongmaize inbreds detected by RFLPs, RAPDs, SSRs, and AFLPs,” Theoreticaland Applied Genetics (1998) at 1248-1255 incorporated herein byreference. SSR technology is more efficient and practical to use thanRFLPs; more marker loci can be routinely used and more alleles permarker locus can be found using SSRs in comparison to RFLPs. SingleNucleotide Polymorphisms may also be used to identify the unique geneticcomposition of the invention and progeny lines retaining that uniquegenetic composition. Various molecular marker techniques may be used incombination to enhance overall resolution.

Maize DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Boppenmaier, et al., “Comparisons among strains of inbreds forRFLPs”, Maize Genetics Cooperative Newsletter, 65:1991, pg. 90, isincorporated herein by reference.

One use of molecular markers is Quantitative Trait Loci (QTL) mapping.QTL mapping is the use of markers, which are known to be closely linkedto alleles that have measurable effects on a quantitative trait.Selection in the breeding process is based upon the accumulation ofmarkers linked to the positive effecting alleles and/or the eliminationof the markers linked to the negative effecting alleles from the plant'sgenome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can is minimize theamount of genome from the donor parent that remains in the selectedplants. It can also be used to reduce the number of crosses back to therecurrent parent needed in a backcrossing program. The use of molecularmarkers in the selection process is often called genetic marker enhancedselection.

Production of Double Haploids

The production of double haploids can also be used for the developmentof inbreds in the breeding program. An F1 hybrid for which PH5DP is aparent can be used to produce double haploid plants. Double haploids areproduced by the doubling of a set of chromosomes (1 N) from aheterozygous plant to produce a completely homozygous individual. Forexample, see Wan et al., “Efficient Production of Doubled Haploid PlantsThrough Colchicine Treatment of Anther-Derived Maize Callus”,Theoretical and Applied Genetics, 77:889-892, 1989. This can beadvantageous because the process omits the generations of selfing neededto obtain a homozygous plant from a heterozygous source.

Use Of PH5DP in Tissue Culture

This invention is also directed to the use of PH5DP in tissue culture.As used herein, the term “tissue culture” includes plant protoplasts,plant cell tissue culture, cultured microspores, plant calli, plantclumps, and the like. As used herein, phrases such as “growing the seed”or “grown from the seed” include embryo rescue, isolation of cells fromseed for use in tissue culture, as well as traditional growing methods.

Duncan, Williams, Zehr, and Widholm, Planta (1985) 165:322-332 reflectsthat 97% of the plants cultured that produced callus were capable ofplant regeneration. Subsequent experiments with both inbreds and hybridsproduced 91% regenerable callus that produced plants. In a further studyin 1988, Songstad, Duncan & Widholm in Plant Cell Reports (1988),7:262-265 reports several media additions that enhance regenerability ofcallus of two inbred lines. Other published reports also indicated that“nontraditional” tissues are capable of producing somatic embryogenesisand plant regeneration. K. P. Rao, et al., Maize Genetics CooperationNewsletter, 60:64-65 (1986), refers to somatic embryogenesis from glumecallus cultures and B. V. Conger, et al., Plant Cell Reports, 6:345-347(1987) indicates somatic embryogenesis from the tissue cultures of maizeleaf segments. Thus, it is clear from the literature that the state ofthe art is such that these methods of obtaining plants are, and were,“conventional” in the sense that they are routinely used and have a veryhigh rate of success.

Tissue culture of maize, including tassel/anther culture, is describedin U.S. 2002/0062506A1 and European Patent Application, publication160,390, each of which are incorporated herein by reference for thispurpose. Maize tissue culture procedures are also described in Green andRhodes, “Plant Regeneration in Tissue Culture of Maize,” Maize forBiological Research (Plant Molecular Biology Association,Charlottesville, Va. 1982, at 367-372) and in Duncan, et al., “TheProduction of Callus Capable of Plant Regeneration from Immature Embryosof Numerous Zea Mays Genotypes,” 165 Planta 322-332 (1985). Thus,another aspect of this invention is to provide cells which upon growthand differentiation produce maize plants having the genotype and/orphysiological and morphological characteristics of inbred line PH5DP.

Progeny of the breeding methods described herein may be characterized inany number of ways, such as by traits retained in the progeny, pedigreeand/or molecular markers. Using the breeding methods described herein,one can develop individual plants, plant cells, and populations ofplants that retain at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 61%,62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%,76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%,90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5% geneticcontribution from inbred line PH5DP. In pedigree analysis the percentagegenetic contribution may not be actually known, but on average 50% ofthe starting germplasm would be expected to be passed to the progenyline after one cross to another line, 25% after another cross to adifferent line, and so on. With backcrossing, the expected contributionof PH5DP after 2, 3, 4 and 5 doses (or 1, 2, 3 and 4 backcrosses) wouldbe 75%, 87.5%, 93.75% and 96.875% respectively. Actual geneticcontribution may be much higher than the genetic contribution expectedby pedigree, especially if molecular markers are used in selection.Molecular markers could also be used to confirm and/or determine thepedigree of the progeny line.

Specific methods and products produced using inbred line PH5DP in plantbreeding are discussed in the following sections. The methods outlinedare described in detail by way of illustration and example for purposesof clarity and understanding. However, it will be obvious that certainchanges and modifications may be practiced within the scope of theinvention.

One method for producing a line derived from inbred line PH5DP is asfollows. One of ordinary skill in the art would produce or obtain a seedfrom the cross between inbred line PH5DP and another variety of maize,such as an elite inbred variety. The F1 seed derived from this crosswould be grown to form a homogeneous population. The F1 seed wouldcontain essentially all of the alleles from variety PH5DP andessentially all of the alleles from the other maize variety. The F1nuclear genome would be made-up of 50% variety PH5DP and 50% of theother elite variety. The F1 seed would be grown and allowed to self,thereby forming F2 seed. On average the F2 seed would have derived 50%of its alleles from variety PH5DP and 50% from the other maize variety,but many individual plants from the population would have a greaterpercentage of their alleles derived from PH5DP (Wang J. and R. Bernardo,2000, Crop Sci. 40:659-665 and Bernardo, R. and A. L. Kahler, 2001,Theor. Appl. Genet 102:986-992). The molecular markers of PH5DP could beused to select and retain those lines with high similarity to PH5DP. TheF2 seed would be grown and selection of plants would be made based onvisual observation, markers and/or measurement of traits. The traitsused for selection may be any PH5DP trait described in thisspecification, including the inbred per se maize PH5DP traits describedherein under the detailed description of inbred PH5DP. Such traits mayalso be the good general or specific combining ability of PH5DP,including its ability to produce hybrids with the approximate maturityand/or hybrid combination traits described herein in under the detaileddescription of inbred PH5DP. The PH5DP progeny plants that exhibit oneor more of the desired PH5DP traits, such as those listed herein, wouldbe selected and each plant would be harvested separately. This F3 seedfrom each plant would be grown in individual rows and allowed to self.Then selected rows or plants from the rows would be harvestedindividually. The selections would again be based on visual observation,markers and/or measurements for desirable traits of the plants, such asone or more of the desirable PH5DP traits listed herein. The process ofgrowing and selection would be repeated any number of times until aPH5DP progeny inbred plant is obtained. The PH5DP progeny inbred plantwould contain desirable traits derived from inbred plant PH5DP, some ofwhich may not have been expressed by the other maize variety to whichinbred line PH5DP was crossed and some of which may have been expressedby both maize varieties but now would be at a level equal to or greaterthan the level expressed in inbred variety PH5DP. However, in each casethe resulting progeny line would benefit from the efforts of theinventor(s), and would not have existed but for the inventor(s) work increating PH5DP. The PH5DP progeny inbred plants would have, on average,50% of their nuclear genes derived from inbred line PH5DP, but manyindividual plants from the population would have a greater percentage oftheir alleles derived from PH5DP. This breeding cycle, of crossing andselfing, and optional selection, may be repeated to produce anotherpopulation of PH5DP progeny maize plants with, on average, 25% of theirnuclear genes derived from inbred line PH5DP, but, again, manyindividual plants from the population would have a greater percentage oftheir alleles derived from PH5DP. Another embodiment of the invention isa PH5DP progeny plant that has received the desirable PH5DP traitslisted herein through the use of PH5DP, which traits were not exhibitedby other plants used in the breeding process.

The previous example can be modified in numerous ways, for instanceselection may or may not occur at every selfing generation, selectionmay occur before or after the actual self-pollination process occurs, orindividual selections may be made by harvesting individual ears, plants,rows or plots at any point during the breeding process described. Inaddition, double haploid breeding methods may be used at any step in theprocess. The population of plants produced at each and any cycle ofbreeding is also an embodiment of the invention, and on average eachsuch population would predictably consist of plants containingapproximately 50% of its genes from inbred line PH5DP in the firstbreeding cycle, 25% of its genes from inbred line PH5DP in the secondbreeding cycle, 12.5% of its genes from inbred line PH5DP in the thirdbreeding cycle and so on. However, in each case the use of PH5DPprovides a substantial benefit. The linkage groups of PH5DP would beretained in the progeny lines, and since current estimates of the maizegenome size is about 50,000-80,000 genes (Xiaowu, Gai et al., NucleicAcids Research, 2000, Vol. 28, No. 1, 94-96), in addition to non-codingDNA that impacts gene expression, it provides a significant advantage touse PH5DP as starting material to produce a line that retains desiredgenetics or traits of PH5DP.

Another embodiment of this invention is the method of obtaining asubstantially homozygous PH5DP progeny plant by obtaining a seed fromthe cross of PH5DP and another maize plant and applying double haploidmethods to the F1 seed or F1 plant or to any successive filialgeneration. Such methods decrease the number of generations required toproduce an inbred with similar genetics or characteristics to PH5DP. SeeBernardo, R. and Kahler, A. L., Theor. Appl. Genet. 102:986-992, 2001.

The utility of inbred maize line PH5DP also extends to crosses withother species. Commonly, suitable species will be of the familyGraminaceae, and especially of the genera Zea, Tripsacum, Coix,Schlerachne, Polytoca, Chionachne, and Trilobachne, of the tribeMaydeae. Potentially suitable for crosses with PH5DP may be the variousvarieties of grain sorghum, Sorghum bicolor (L.) Moench.

As is readily apparent to one skilled in the art, the foregoing are onlysome of the various ways by which the inbred can be obtained by thoselooking to use the germplasm. Other means are available, and the aboveexamples are illustrative only.

INDUSTRIAL APPLICABILITY

Maize is used as human food, livestock feed, and as raw material inindustry. The food uses of maize, in addition to human consumption ofmaize kernels, include both products of dry- and wet-milling industries.The principal products of maize dry milling are grits, meal and flour.The maize wet-milling industry can provide maize starch, maize syrups,and dextrose for food use. Maize oil is recovered from maize germ, whichis a by-product of both dry- and wet-milling industries.

Maize, including both grain and non-grain portions of the plant, is alsoused extensively as livestock feed, primarily for beef cattle, dairycattle, hogs, and poultry.

Industrial uses of maize include production of ethanol, maize starch inthe wet-milling industry and maize flour in the dry-milling industry.The industrial applications of maize starch and flour are based onfunctional properties, such as viscosity, film formation, adhesiveproperties, and ability to suspend particles. The maize starch and flourhave application in the paper and textile industries. Other industrialuses include applications in adhesives, building materials, foundrybinders, laundry starches, explosives, oil-well muds, and other miningapplications.

Plant parts other than the grain of maize are also used in industry: forexample, stalks and husks are made into paper and wallboard and cobs areused for fuel and to make charcoal.

The seed of inbred maize line PH5DP, the plant produced from the inbredseed, the hybrid maize plant produced from the crossing of the inbred,hybrid seed, and various parts of the hybrid maize plant and transgenicversions of the foregoing, can be utilized for human food, livestockfeed, and as a raw material in industry.

A method of introducinga desired trait into maize inbred line PH5DP comprising: (a) crossing aPH5DP plant grown from PH5DP seed, representative seed of which has beendeposited under ATCC Accession No. PTA-4872, with a plant of anothermaize line that comprise a desired trait to produce F1 progeny plants,wherein the desired trait is selected from the group consisting of malesterility, herbicide resistance, insect resistance, disease resistanceand waxy starch; (b) selecting F1 progeny plants that have the desiredtrait to produce selected F1 progeny plants; (c) crossing the selectedprogeny plants with the PH5DP plants to produce backcross progenyplants; (d) selecting for backcross progeny plants that have the desiredtrait and physiological and morphological characterstics of maize inbredline PH5DP listed in Table 1 to produce selected backcross progenyplants; and (e) repeating steps (c) and (d) three or more times insuccession to produce selected fourth or higher backcross progeny plantsthat comprise the desired trait and all of the physiological andmorphological characteristics of maize inbred line PH5DP listed in Table1 as determined at the 5% significance level when grown in the sameenvironmental conditions.
 26. A plant produced by the method of claim25, wherein the plant has the desired trait and all of the physiologicaland morphological characteristics of maize inbred line PH5DP listed inTable 1 as determined at the 5% significance level when grown in thesame environmental conditions.
 27. The plant of claim 26, wherein thedesired trait is herbicide resistance and the resistance is conferred toan herbicide selected from the group consisting of imidazolinone,sulfonylurea, glyphosate, glufosinate, L-phosphinothricin, triazine andbenzonitrile.
 28. The plant of claim 26, wherein the desired trait isinsect resistance and the insect resistance is conferred by a transgeneencoding a Bacillus thuringiensis endotoxin.
 29. The plant of claim 26,wherein the desired trait is male sterility and the trait is conferredby a cytoplasmic nucleic acid molecule that confers male sterility. 30.A method of modifying fatty acid metabolism, phytic acid metabolism orcarbohydrate metabolism in maize inbred line PH5DP comprising: (a)crossing a PH5DP plants a PH5DP plant grown from PH5DP seed,representative seed of which has been deposited under ATCC Accession No.PTA-4872, with a plant of another maize line that comprise a nucleicacid molecule encoding an enzyme selected from the group consisting ofphytase, fructosyltransferase, levansucrase, alpha-amylase, invertaseand starch branching enzyme or encoding an antisense stearyl-ACPdesaturase; (b) selecting F1 progeny plants that have said nucleic acidmolecule to produce selected F1 progeny plants; (c) crossing theselected progeny plants with the PH5DP plants to produce backcrossprogeny plants; (d) selecting for backcross progeny plants that havesaid nucleic acid molecule and physiological and morphologicalcharacteristics of maize inbred line PH5DP listed in Table 1 to produceselected backcross progeny plants; and (e) repeating steps (c) and (d)three or more times in succession to produce selected fourth or higherbackcross progeny plants that comprise said nucleic acid molecule andhave all of the physiological and morphological characteristics of maizeinbred line PH5DP listed in Table 1 as determined at the 5% significancelevel when grown in the same environmental conditions.
 31. A planthaving modified fatty acid metabolism, modified phytic acid metabolismor modified carbohydrate metabolism produced by the method of claim 30,wherein the plant comprises the nucleic acid molecule and has all of thephysiological and morphological characteristics of maize inbred linePH5DP listed in Table 1 as determined at the 5% significance level whengrown in the same environmental conditions.
